We don't have a master list of trailer bearings, so the best way to determine the correct bearings and seal for your trailer is to remove the old bearings and check for the part numbers on the bearings. Finding the part numbers will help us find the exact replacement bearings.
If you are unable to find the numbers on the face of the bearings, you will want to measure the spindle surface with a digital caliper, like # PTW80157, to determine the measurements for the bearings and the seals. Using the inner and outer diameter measurements is another great way to determine the correct replacement bearings.
I have attached a diagram showing where to measure the spindle to determine the correct replacement bearings and seals for you. This will keep you from removing the current seal and bearings if desired for the time being.
If you will let me know the part numbers of your bearings and seal or the measurements from your spindle, I will be happy to find the correct replacement part numbers for you.
